Source ontology | Industrial Data Ontology |
is primitive | false |
natural language definition | An 'object' that provides a required 'function'. |
semi-formal natural language axiom | If x is a 'functional object', then x is an 'object' that 'has function' some 'function'. |
usage note | A password must be concretized, this is done when it is entered, the password performs the function of unlocking the computer. The password participates in the unlocking process through its concretization. |
A "tag" (see [[term:tag]]), when included in an IDO asset model, should in general have a type that is subclass of both 'functional object' and 'artefact'. | |
Artefact types tend to be described primarily in terms of 'function'; for example, the "minimal" definition of a pump would be, "a physical artefact, the function of which is to pump (to be the active participant in a pumping activity)". This kind of definition places no restriction on physical make-up and is suitable for a subclass of 'functional object'. Note that the activity type of 'pumping' is here a precursor to the definition of the physical object type 'pump'. A taxonomy of pump classes should extend from a class 'pump' defined solely in terms of function, as above. | |
